  I am trying to run the example https://optics.ansys.com/hc/en-us/articles/18254409091987 and generate an h5 file for Zemax in Lumerical version 2022 R2.3. I am receiving the following error h5write is not a valid function or variable name. What should I do?
  Kind regards,
  Maryna

  Hi Maryna,
  What happens if you run this ?h5write; in the Script Prompt?

  Hi Maryna,
  I checked with the team internally. This script command was implemented in the 2023 R2.1 release. So, you would have to install 2023 R2.1 or 2023 R2.2 to be able to use this script command.

  Hi Amrita,
  I have follow-up questions:
  1. Locate the 3 .dll files lumhdf5.dll, lumhdf5_hl.dll, and zlib1.dll in the install folder of Lumerical and copy them in the installation folder of Zemax
  What exact folder should I copy to these dll's? I copied it to Zemax>DLL>Surfaces as in step 3. Is it correct?
  1. Open the file metalens_R10mm_f300mm.zprj and see how the metalens is defined
  I have the lates Zemax Optics Studio, and when I am trying to open this file, the extension of this file is not in the list. How can I open this file in OpticStudio?
